Chemistry Year 12 - Module 6 - Lesson 17
★ Titration & Indicator Mastery — Curves, Selection & Band 6 Responses
1. Key Ideas
★ Consolidation — Deepening L14–L16. Four students have been given the same titration curve and asked to identify the equivalence point, name a suitable indicator, and read the pKa. Only one student gets all three correct. Before reading on — can you identify who, and precisely diagnose what each of the others got wrong?
- The five characteristic regions of a titration curve and how to identify each
- Why the two most common student errors (EP at pH 7 + methyl orange) are causally linked
2. Success Criteria
By the end, you should be able to:
- The five characteristic regions of a titration curve and how to identify each
- The three mandatory features of a correct indicator justification
- Why EP ≠ pH 7 for weak acid + strong base

5. Short Answer Questions
1. Explain this lesson goal in your own words: "The five characteristic regions of a titration curve and how to identify each". Use one specific example from the lesson.
2. Apply this idea to a new example: "The three mandatory features of a correct indicator justification". Show your reasoning clearly.
3. Analyse why this idea matters for understanding ★ Titration & Indicator Mastery — Curves, Selection & Band 6 Responses: "Why EP ≠ pH 7 for weak acid + strong base".
6. Extend: Apply the Idea
A student gives a memorised answer about ★ Titration & Indicator Mastery — Curves, Selection & Band 6 Responses but does not use evidence or reasoning.
Improve the answer by writing a stronger response that uses accurate terminology, a relevant example and a clear explanation.
